Automorphic formIn harmonic analysis and number theory, an automorphic form is a well-behaved function from a topological groupG{\displaystyle G} to the complex numbers (or complex vector space) which is invariant under the action of a discrete subgroupΓ<G{\displaystyle \Gamma <G} of the topological group. Automorphic forms are a generalization of the idea of periodic functions in Euclidean space to general topological groups.
Algebraic number theoryAlgebraic number theory is a branch of number theory that uses the techniques of abstract algebra to study the integers, rational numbers, and their generalizations. Number-theoretic questions are expressed in terms of properties of algebraic objects such as algebraic number fields and their rings of integers, finite fields, and function fields.
Local fieldIn mathematics, a local field is a locally compactHausdorff non-discretetopological field. Local fields find many applications in algebraic number theory, where they arise naturally as completions of global fields. Moreover, tools like integration and Fourier analysis are available for functions defined on local fields. Given a local field, an absolute value can be defined on it which gives rise to a complete metric that generates its topology.

Group representationIn the mathematical field of representation theory, group representations describe abstract groups in terms of bijective linear transformations of a vector space to itself (i.e. vector space automorphisms); in particular, they can be used to represent group elements as invertible matrices so that the group operation can be represented by matrix multiplication.
Galois groupIn Galois theory, a branch of abstract algebra, the Galois group of a certain type of field extension is a symmetry group characterizing how it extends the base field. Each element of the Galois group is a transformation of the field extension which leaves each element of the base field fixed.
ConjectureIn mathematics, a conjecture is a proposition that is proffered on a tentative basis without proof. Some conjectures, such as the Riemann hypothesis or Fermat's conjecture (now a theorem, proven in 1995 by Andrew Wiles), have shaped much of mathematical history as new areas of mathematics are developed in order to prove them.
Number theoryBranch of pure mathematicsThe distribution of prime numbers, a central point of study in number theory, illustrated by an Ulam spiral. It shows the conditional independence between being prime and being a value of certain quadratic polynomials.Number theory is a branch of mathematics devoted primarily to the study of the integers and arithmetic functions.
Robert LanglandsRobert Phelan Langlands (; born October 6, 1936) is a Canadian mathematician. He is best known as the founder of the Langlands program, a vast web of conjectures and results connecting representation theory and automorphic forms to the study of Galois groups in number theory, for which he received the 2018 Abel Prize. He is emeritus professor and occupied Albert Einstein's office at the Institute for Advanced Study in Princeton, until 2020 when he retired.
MathematicsMathematics is a field of knowledge concerned with abstract concepts such as numbers, geometric shapes, sets, functions, and probabilities. It uses logical reasoning and proof to study and establish their properties, often expressed as theorems, formulas, and equations. Mathematics is used to model and solve problems in science, engineering, technology, economics, and everyday life.
